Cardinals manager Oliver Marmol said Thursday that Contreras is likely to be sidelined for about 10 weeks after successful surgery Wednesday to repair a fractured left forearm, Katie Woo of The Athletic reports.

Contreras had offered a 6-to-8 week timetable himself earlier this week, but indications are that it will probably be a bit longer than that. It puts the catcher out likely until right around the All-Star break. Ivan Herrera will operate as the Cardinals' primary catcher while Contreras is sidelined, with Pedro Pages backing him up.

Herrera isn't in the Cardinals' lineup for Thursday's game against the Brewers, John Denton of MLB.com reports.

Herrera will get a day off Thursday after going 2-for-4 during Tuesday's game against the Mets. In his absence, Pedro Pages will pick up a start behind the plate and bat eighth.

Sabol will serve as the Giants' designated hitter and No. 7 hitter in Thursday's game against the Rockies, Shayna Rubin of the San Francisco Chronicle reports.

Sabol will pick up his fourth start in five games, though he'll be filling a non-defensive role Thursday after each of the prior three starts came at catcher. The 26-year-old should continue to see the bulk of the action behind the dish while both Patrick Bailey (concussion) and Tom Murphy (knee) are on the injured list. Sabol has gone 6-for-12 with a double and a walk since being called up from Triple-A Sacramento last weekend.

Stephenson is out of the lineup for Thursday's game against the Diamondbacks.

Stephenson was behind the plate for both of the past two days and the Reds are closing out their series in Arizona with an afternoon game, so he'll receive a breather Thursday. Luke Maile will serve as the Reds' starting catcher in his place.

Diaz went 2-for-4 with a home run and three RBI in Wednesday's loss to the Giants.

Diaz drove in Colorado's third run of the game with an infield single in the bottom of the fifth and later added a two-run shot in the ninth to bring his team back within two runs of the Giants, though his effort would fall short. It marked the catcher's third multi-hit game already this month, and he's now hit safely in five of his last six contests. The home run was only Diaz's third of the season, though he's now batting .348 in May with four RBI and three extra-base hits.

Moreno is absent from the lineup for Thursday's game in Cincinnati.

Moreno returned to action Wednesday after missing one game due to illness, but he'll begin Thursday's afternoon tilt on the bench. Tucker Barnhart will pick up the start at catcher.

Atlanta manager Brian Snitker said Wednesday that Murphy (oblique) has progressed to hitting in the batting cage, David O'Brien of The Athletic reports.

Murphy's recovery from a Grade 1 left oblique strain has inched along at a snail's pace, but he's finally making noteworthy progress. Given that he's already missed nearly six weeks of action, he will no doubt require a handful of minor-league rehab games before returning from the 10-day injured list.

Moreno (illness) will start at catcher and bat seventh in Wednesday's game in Cincinnati.

Moreno missed Tuesday's 6-2 win because he was under the weather, but he's evidently feeling better and ready to give it a go Wednesday. The young catcher is still searching to find his offensive rhythm this season, as he's yet to slug a home run and will carry a .662 OPS into play Wednesday.

Amaya is out of the lineup for Wednesday's game against the Padres.

Amaya will rest for the series finale after he started at catcher in four of the Cubs' previous five games. Yan Gomes will step in behind the dish Wednesday.

Herrera will serve as the Cardinals' designated hitter and cleanup batter in Wednesday's game against the Mets.

Though he'll be included in the lineup in a non-defensive role Wednesday, Herrera is expected to serve as the Cardinals' primary backstop for the foreseeable future after Willson Contreras was placed on the 10-day injured list with a fractured forearm, an injury that will likely keep him out for 6-to-8 weeks. Pedro Pages was called up from Triple-A Memphis in a corresponding move and will start behind the plate Wednesday, but Herrera should see the bulk of the work at catcher while Contreras is on the shelf. Herrera has logged 76 plate appearances so far this season, hitting .232 with three home runs, 11 RBI and seven runs.
