Coach Frank Reich said the starter would get in limited practice reps today.
Brissett exited Sunday's loss in Pittsburgh early in the second quarter with a knee injury after guard Quinton Nelson fell into his left leg. The 26-year-old tried to shake off the injury and return, but the Colts held him out due to lack of lateral mobility.
The MRI on Monday came back with positive news, indicating Brissett suffered a sprained MCL.
If Brissett can't go, or Indy decides to play it safe with the QB, veteran Brian Hoyer proved Sunday he is more than capable of moving Reich's offense. We'll have a better idea about Brissett's status as the week progresses.
