Per Angelique Chengelis' Twitter:
"RR says Mouton and Martin practiced Tuesday. Doing better. Taylor Lewan & Shaw dealing with concussion-like symptoms."
"UM right tackle Dorrestein is fine. If Lewan can't go, Mark Huyge, who has started for Dorrestein, could start at LT."
I knew about Shaw but this is the first I have heard anything about Lewan. Let's hope they're both alright.
