Previewing Monday's Bills scrimmage

The Buffalo Bills are set to host their first instra-squad scrimmage of training camp on Monday evening at St. John Fisher College, from 6-9 p.m. ET.

It was noted in this space earlier Monday the Bills left guard position will be one to monitor in the scrimmage, as it will be an opportunity for both Doug Legursky and Colin Brown to square off against defensive coordinator Mike Pettine's multiple, pressure scheme.

Here are a few other areas to watch tonight, which is a ticketed event:

1. Will Kolb be on the field? Head coach Doug Marrone said after Sunday's practice that the Bills are "trying to get" quarterback Kevin Kolb back into action Monday night. Kolb slipped on a wet rubber mat between practice fields on Saturday, "bumping" his knee, according to Marrone. Even Kolb is in uniform, it will be worth monitoring if the injury affects his mobility in what could be an up-tempo Bills offense. Kolb has struggled at times through the first week of camp.

2. Who participates? With 90 players on the roster, getting a look at every player in live action can be difficult. Marrone said Saturday that his staff would meet and decide which players take part in the scrimmage. The best guess from this standpoint is that the team limits or holds out players who they already have a good feel for on the roster. It's a balance for the coaching staff between getting their best players prepared for the season and giving their less experienced players a chance to compete for back-end roster spots. At this point in camp, expect the focus to be on the latter.

3. Will someone stand out at receiver? The Bills have a stable of younger players competing for playing time at wide receiver, including a pair of draft picks (Robert Woods and Marquise Goodwin). With top target Steve Johnson (hamstring) not participating, it's a prime opportunity for Woods or Goodwin to challenge T.J. Graham for a bigger role in the offense, as well as a chance for an undrafted rookie like Da'Rick Rogers to make a case for a roster spot.
