Horwitz (hamstring) was diagnosed with a concussion Tuesday after being hit in the helmet with a pitch while on a rehab assignment at Single-A Bradenton, Aiden Stepansky of MLB.com reports.

Horwitz's activation from the 10-day injured list had appeared imminent, but his status is now up in the air as a result of the head injury. The first baseman initially landed on the IL in late June due to a left hamstring strain, but he appears to have made a full recovery from that injury. Horwitz will remain on the IL for now and might need to play more rehab games once he clears concussion protocol.

Locklear is out of the lineup for Tuesday's game against the Pirates.

Locklear will open Tuesday's contest on the bench, but he seems to have worked his way into a part-time role in the Arizona lineup after going 4-for-14 with a home run, a stolen base, a walk, four RBI and three runs while starting in four of the previous five contests. Tim Tawa will get the nod at first base Tuesday, but he's capable of playing all over the infield and outfield if Arizona wants to clear room in the lineup for Locklear.

Tena is absent from the lineup for Tuesday's contest versus the Blue Jays.

The left-handed-swinging Tena had drawn five straight starts against righties (with four of them coming from the designated hitter slot), but he'll begin this one on the bench as the Blue Jays send righty Shane Bieber to the hill. James Wood will fill the DH spot Tuesday, and Daylen Lile, Jacob Young and Dylan Crews will patrol the outfield.

Vivas will start at third base and bat eighth in Tuesday's game versus the Blue Jays.

Following the trade of Curtis Mead, the left-handed-hitting Vivas has started at third base both times the Nationals have faced a right-hander. Brady House drew a start against a lefty, but it seems Vivas is currently manager Blake Butera's preferred option at the hot corner versus righty hurlers. The 25-year-old Vivas is slashing .240/.321/.339 with three homers and a 21:32 BB:K across 76 contests for the Nats this season.

House is not in the lineup for Tuesday's game against the Blue Jays.

House started against a lefty Sunday after being recalled from Triple-A Rochester, but he'll now sit out a second straight day versus a righty. While the 23-year-old might not be in a strict short-side platoon with Jorbit Vivas, it seems the left-handed-hitting Vivas is the preferred option at third base versus righties.

Harvey (finger) has gone 0-for-6 with three walks, one stolen base and one run in two games for Single-A Lake Elsinore since being activated from the 60-day injured list Saturday.

Harvey had been on the shelf since May 26 after fracturing a finger on his left hand. The 20-year-old catcher has been limited to just 17 games with Lake Elsinore this season due to injury but has been productive when available, slashing .302/.448/.396 with five doubles and six stolen bases.

Warren (forearm) will begin a rehab assignment with Single-A St. Lucie on Tuesday, Anthony DiComo of MLB.com reports.

Warren has been cleared to test things out in games after missing the past three weeks of action with a right forearm strain. He'd been effective before getting hurt, holding a 2.45 ERA and 36:16 K:BB over 33 innings. Warren shouldn't need too many rehab outings before being reinstated to the active roster.

Sanoja is absent from the lineup for Tuesday's contest versus the Phillies.

Sanoja will begin the festivities on the bench for the second time over the Marlins' last three games. Graham Pauley is grabbing a start at third base in Sanoja's stead.

Scott won't pitch as scheduled Tuesday against Atlanta since the game was postponed due to forecasted inclement weather.

The game will be made up via a doubleheader Wednesday, and Scott will presumably take the mound in one of those contests. The 27-year-old righty has yet to complete six frames in any of his 14 starts this season, but he's still been effective with a 3.13 ERA, 1.26 WHIP and 78:29 K:BB over 63.1 innings.

Sale won't pitch as scheduled Tuesday against the Mets since the game was postponed due to forecasted inclement weather.

The contest will be made up via a doubleheader Wednesday, with Sale likely to start one of those contests. In two starts since the All-Star break, the veteran left-hander has given up just three runs on seven hits with a 17:1 K:BB across 13 innings.
