Ohio State linebacker Tuf Borland suffered an Achilles tendon injury in practice last week, Ohio State coach Urban Meyer said Monday.
Meyer said Borland's season is not in jeopardy at this point and expects him to return.
Borland, a redshirt sophomore, started nine games for the Buckeyes at middle linebacker last season and was expected to be the Buckeyes' starting middle linebacker this season.
With Borland sidelined, the Buckeyes could now have an entirely new starting linebacker corps from the end of last season. Redshirt junior Justin Hilliard and sophomore Baron Browning are the top candidates to take Borland's place at the middle linebacker spot, with Hilliard taking first-team repetitions during Monday's practice. Malik Harrison is working as the first-team strongside linebacker this spring, while Keandre Jones has been running as the first-team weakside linebacker.
