Tyler Austin will be sidelined “for months” after undergoing surgery on his right knee.

The Cubs signed Austin to a one-year contract back in December, and he was one of the favorites to land a bench spot on the Opening Day roster. It’s unclear what happened, but Cubs manager Craig Counsell simply noted that Austin would be out for months. That could open the door for both Michael Conforto and Chas McCormick to make the Cubs, with Matt Shaw perhaps getting some starts at first base against lefties to begin the season. Of course, Cubs 1B prospect Jonathan Long also hit .305/.404/.479 with 20 home runs in 140 Triple-A games last year and hits right-handed.
