Syracuse might be without cornerback Brandon Reddish when it hosts No. 3 Clemson in its Atlantic Coast Conference debut on Oct. 5, SU head coach Scott Shafer announced Wednesday.

“Brandon Reddish will probably be questionable for Clemson with a lower-leg injury,” Shafer said during the ACC coaches’ teleconference.

Reddish — who mixes in with Ri’Shard Anderson at cornerback opposite Keon Lyn — and starting defensive end Robert Welsh both missed the second half of SU’s 52-17 win against Tulane last week. Welsh, who had to be helped off the field and was unable to put any weight on his left leg, is returning to practice this week, Shafer said.

“Robbie Welsh is doing well,” Shafer said. “We had a scare with him, but he’s back.”

Also returning to practice this week is offensive lineman Kyle Knapp, who suffered a head injury during training camp and has yet to play for the Orange this season.

Shafer said practices this week will focus primarily on lifting and running.

He was not asked about senior kicker Ross Krautman, who will have season-ending surgery on a hip-related injury and is eligible to apply for a medical hardship waiver.
