Kevin Kolb will return to Bills' practice Friday

The free agent acquisition has missed practice this week due to a death in the family, but head coach Doug Marrone says that won't affect his chances at winning the QB competition.

Bills quarterback Kevin Kolb will return to practice on Friday, according to head coach Doug Marrone, but it is not yet known if he will play in Buffalo's preseason opener.  Kolb has been away from the training facilities due to a death in the family and will have missed a total of five practices by the time he returns. Over the weekend, Kolb tweaked his knee, taking him away from the practice field.

The veteran quarterback is currently in a competition with rookie E.J. Manuel for the starting position in Buffalo, and Marrone says that it wouldn't be fair to hold this week against Kolb due to the missed practices:

"We’re still in competition and our goal is to be equal and be fair and there are a lot of things that go into that. Right now EJ has approximately 100 more snaps. I think sometimes it depends on what our thoughts are with the people around them too to make sure when we look at things we do it in a fair manner when we do those evaluations."

The Bills drafted Manuel out of Florida State with the 16th overall pick and also signed Kolb to a two-year, $13 million contract. The hope is that one of them will be a significant improvement over Ryan Fitzpatrick, the 2012 starter who struggled last year and was released.

Kolb made five starts with the Arizona Cardinals last season, completing 59.6 percent of his passes for 1,169 yards, eight touchdowns, three interceptions and a QB rating of 86.1.  But Kolb suffered a rib injury in Week 6 that caused him to miss the rest of the year, and the Cardinals released him after failing to come to an agreement on a contract negotiation.

Buffalo travels to Indianapolis to play the Colts in its preseason opener on Sunday at 1:30 ET.
