PITTSFORD, N.Y. – Buffalo Bills quarterback Kevin Kolb has taken a big step toward being cleared to make his preseason debut against the Minnesota Vikings on Friday.
Second-year receiver T.J. Graham, meanwhile, is unlikely to play because of a groin injury.
Those were among the updates coach Doug Marrone provided after practice Tuesday.
Marrone said Kolb is on track to play Friday based on how the seventh-year player performed in his second practice since twisting his left knee. Kolb missed eight days and Buffalo's preseason-opener at Indianapolis on Sunday.
Kolb is competing with rookie first-round draft pick EJ Manuel for the starting job.
Graham was held out of practice a day after he was hurt.
Starting safety Aaron Williams limped off and did not return after experiencing what Marrone called cramps.
