Texas Rangers shortstop Corey Seager (back) was absent from the starting lineup for the third straight game on Sunday. The team is still calling the injury minor, but Seager did undergo an MRI over the weekend. Seager is now heading back to Arlington to see a back specialist about his injury. With that being said, Seager won't be available for the first game of the series in Colorado, starting on Monday. Ezequiel Duran has made multiple starts at shortstop and figures to continue holding down the fort until Seager is ready to return. Fantasy managers will need to check back for another update on Seager, but he'll likely still miss a few more games.

St. Louis Cardinals shortstop Masyn Winn (knee) was forced to make an early exit from Sunday's game against the Kansas City Royals. Winn appeared to tweak his knee while running out a fielder's choice in the seventh inning. He was pulled out of the game for a pinch-hitter and will undergo further testing. Winn finished the day going 1-for-2 at the plate with a single and a hit by pitch. If Winn does end up missing any action, Cesar Prieto would likely get a chance to play some shortstop. Fantasy managers will need to check back for another update on Winn's status.

Chicago White Sox catcher Kyle Teel (hamstring, knee) suffered a setback during a rehab game at Triple-A Charlotte on Saturday. Teel reportedly tweaked his knee while taking a swing during Saturday's game. He appeared to be nearing his season debut, but will now need a few more games to ramp up. The White Sox plan to re-evaluate him on Tuesday, so fantasy managers should get a better idea of his timetable after that. The hope is that he'll be back in the mix on the South Side by the end of May. Teel hasn't played this season due to injury, but is worth a look in deep leagues once he's ready to play in the big leagues.

Boston Red Sox outfielder Roman Anthony (wrist) is scheduled to begin swinging the bat by hitting flips on Monday, according to Jen McCaffrey. This is the first time that Anthony has swung the bat since landing on the 10-day Injured List earlier this month. The expectation is that he'll need to face live pitching before he's cleared to return to the Red Sox roster. The team should give a better timetable on his return as he makes progress. The hope is that Anthony can return before the end of May, but fantasy managers should check back later in the week for another update on his status.
