Marrone unsure on Kevin Kolb's status

Back in December, Buffalo Bills coach Doug Marrone said that he had not spoken to quarterback Kevin Kolb, who was placed on injured reserve in August.

Nearly two months later, Marrone said he is still not sure of Kolb's plans. Kolb, 29, suffered at least his third career concussion in the third game of the preseason, leaving his playing future in doubt.

"He's under contract and I'm not aware of really what exactly is going on right now, whether he's planning to come back, whether he's not going to come back," Marrone told WGR 550 on Friday. "I have not been informed of anything to that nature."

While it's unclear if general manager Doug Whaley has been in contact with Kolb, the Bills have a decision on their veteran quarterback coming soon. According to ProFootballTalk.com, he is due a $1 million roster bonus on the third day of the 2014 league year, which is March 13. If he is on the roster at that time, Kolb will earn that bonus, so the Bills would need to release him before then (or restructure his contract) to avoid that charge.

Kolb currently has the 10th-highest cap number for the Bills, at $3.6 million against their 2014 salary cap. Releasing Kolb before March 13 would result in the savings of his $2 million base salary as well as his $1 million roster bonus. He also has a $100,000 offseason workout bonus, per ProFootballTalk.com, that would not have to be paid if he's released.

Marrone told WGR 550 on Friday that the Bills are keeping their options open at quarterback.

"I think what we did was we set ourselves up, we can go in any direction, meaning coaching staff-wise," Marrone said. "So we brought in a quarterbacks coach [Todd Downing]. We have a senior adviser in Jim Hostler. I basically have three coaches on this staff now that have coached that position and coached that quarterback, two having coordinated here in the NFL. I've set it up so we have the ability to go either way."
