SAN DIEGO -- Mike McCoy had enough.

Peppered with questions this week by reporters, asking for an update on the contract dispute between first-round pick Joey Bosa and the San Diego Chargers, McCoy indicated it was time to move on to another subject.

"We've gone back and forth on this enough," the head coach said. "I'm coaching the guys that are here. And when he gets here, he'll be part of our team."

Chargers general manager Tom Telesco expressed a similar view in an interview with Xtra 1360 Fox Sports radio.

"I really don't want to get into a play-by-play of everything," Telesco said. "The next update will be when it's done. It doesn't really matter if it's close right now or far away -- it's not done yet."

In Day 13 of the stalemate -- the longest a draft pick has gone unsigned since the current collective bargaining agreement was ratified in 2011 -- Bosa's contract dispute has grown into a national topic of discussion.

Earlier this week, Bosa's mother took to social media to vent her frustration. The post, which was later removed, was written in response to a note from a Facebook user who said he hoped "it turns out well for your son. Chargers are horrible at stopping the running game."

Bosa's mother, Cheryl, wrote in response: "It bums me out for him so much. Wish we pulled an Eli Manning on draft day."

McCoy was asked this week what he thought about the comments on social media.

"I was told about the comments, but I'm very pleased with the 89 guys that are here," McCoy said. "We're going to coach the guys that are here and keep on rolling."

The two sides have not talked since July 28. There appears to be no end in sight, but Telesco believes a compromise eventually will be reached, with Bosa signing a contract and in camp.

"Well, there has to be at some point," Telesco said. "It's important to us. We drafted him for a reason -- we want him here. There are no two people here that want him here more than me and Coach McCoy.

"He's someone we took for a reason. We took him to help this football team. We have to get it done some way, somehow. There's just a hurdle we just can't get over that's hindering negotiations right now. No one wants it done more than we do."

Selected No. 3 by San Diego in this year's draft, Bosa remains the only first-round pick who has not signed. Bosa's father, John, also was a holdout as an NFL rookie. John Bosa was a defensive lineman drafted No. 16 by the Dolphins in 1987 and held out 41 days before signing his rookie contract, according to ESPN Stats & Information.

The two sides remain at an impasse over offset language and the earlier payment of deferred signing bonus money. The Chargers had until Tuesday to trade Joey Bosa's rights, but the Chargers moved past the deadline this week without ever considering a trade.

Veteran tight end Antonio Gates can relate to Bosa's situation because he also dealt with a contract impasse with the Chargers in 2005. Gates said at some point a player has to decide when it's time to play football. Gates said he eventually stepped in and got his contract stalemate resolved.

"It's tough, because as a competitor you want to be here," Gates said. "I think the biggest thing is you just don't want to lose the trust of your teammates. To me, that was something that was bothering me in the times I did sit out and had contract negotiations.

"Over time, sometimes too you have to step in as a man and say, 'This is what it's going to be.' Whether or not it's a miscommunication with the general manager or the agent -- whatever it is -- at the end of the day, it's your life, your career. You know what's best for you and what you need. You still have to have that tunnel vision and be able to perform at the highest level."
