My source says Mallett strained / aggravated his pectoral muscle last week (the one he had surgery on last season)...which is why he missed a practice day last week. Obrien agreed to let him try to play thru it....this is why a number of his passes dropped short into turf....They're doing daily treatment on it and think the muscle is responding & will be much better by Colts game....This is why Obrien is not benching him....He knows Mallett was trying to play thru the pain & doesn't feel he should bench him over a temporary (hopefully) injury....However, if for any reason the muscle is not 100% by Colts game day Obrien could/would hold Mallett out & start Hoyer.
