Quero has been on the 7-day injured list since Aug. 17 due to a back injury, James Fegan of SoxMachine.com reports.

The club has yet to reveal a timetable for Quero's return, and Paul Janish, Director of Player Development, stated Monday that the backstop will likely remain out a bit longer, per Fegan. "At this juncture of the season, we just need to make sure that he's completely healthy," said Janish. Quero was being considered for a September promotion prior to suffering the injury, and his current placement on the IL could prevent him from making his big-league debut if he's not activated in the near future.

Romo is out of the lineup for Monday's game against the Marlins.

Romo will get a breather Monday after he picked up starts behind the plate both of the past two days. Jacob Stallings will handle catching duties for the Rockies in the series opener.

Jeffers is out of the lineup for Monday's game against Atlanta.

After leaving late in Friday's 6-1 loss to the Cardinals due to a right hand injury, Jeffers returned to the lineup for the series finale Sunday, catching all nine innings of the Twins' 3-2 loss. The Twins haven't indicated that Jeffers emerged from the contest with any sort of setback, as his absence from the lineup a day later is likely just a result of him being in a near-even timeshare behind the plate with Christian Vazquez, who draws the starting nod Monday.

Murphy is out of the lineup for Monday's game against the Twins.

Travis d'Arnaud returned to the lineup Saturday after missing about a week of action with a wrist injury, so Murphy appears set to move back into more a timeshare at catcher after he had started behind the plate in six of the past seven contests. Murphy has posted a .633 OPS in August, roughly in line with his disappointing .665 mark for the season.

Rogers is absent from Monday's lineup against the White Sox.

Dillon Dingler will start behind home plate for the second straight game. Since the beginning of August, Rogers has slashed .167/.205/.405 with five runs scored, two home runs and 11 RBI over 44 plate appearances.

The Pirates recalled Davis from Triple-A Indianapolis on Monday.

Davis will receive another opportunity as a result of Joey Bart (hamstring) landing on the 10-day injured list. The 24-year-old has managed a .503 OPS in 29 games in the majors this season but had been hitting well of late with Indianapolis with a .939 OPS and a couple of home runs over his last 12 contests. Davis should share catching responsibilities with Yasmani Grandal while Bart is sidelined.

The Pirates placed Bart on the 10-day injured list Monday with a left hamstring strain.

Bart suffered the injury during Sunday's game against the Reds while attempting to beat out an RBI groundout. The severity of the strain is not known, though general manager Ben Cherington expressed optimism that Bart's injury is "minor" and won't keep him from returning from the IL this season, per Andrew Destin of the Pittsburgh Post-Gazette. The Pirates recalled Henry Davis from Triple-A Indianapolis to take Bart's roster spot, and Davis should share catching duties with Yasmani Grandal for the duration of Bart's absence.

Pages is not in the lineup for Monday's game versus the Padres, Jeff Jones of the Belleville News-Democrat reports.

Pages and Ivan Herrera will handle the catching duties with Willson Contreras (finger) on the injured list, with Pages likely to see better than a 50-50 share. Herrera will get the start behind the dish for the Cardinals' series opener against San Diego.

Naylor is out of the lineup for the first game of Monday's doubleheader with the Royals.

Austin Hedges will draw the start at catcher for the early game while the Royals send a lefty (Cole Ragans) to the hill. Right-hander Alec Marsh is starting for Kansas City in the nightcap, so expect the lefty-hitting Naylor to settle back in behind the dish for that contest.

Stubbs went 4-for-4 with a triple, a double, one RBI and three runs scored in Sunday's 11-3 win over Kansas City.

Stubbs tripled and scored in the third inning before doubling in a run and scoring again in the sixth. He capped off his big day in the eighth inning with a single and another run scored. Stubbs is now slashing .216/.310/.281 with six extra-base hits through 158 plate appearances this season, but his starting opportunities are expected to remain fairly limited while top backstop J.T. Realmuto is available.
