SAN DIEGO -- Asked if he was surprised the contract impasse between the San Diego Chargers and unsigned first-round selection Joey Bosa had come to this point, general manager Tom Telesco offered a one-word answer.

"Yes," he said in a reserved tone, after the Chargers announced they had pulled their contract offer to Bosa, the No. 3 overall pick in the draft.

Now that the damage has been done and the Chargers probably will not have Bosa for the season opener against the Kansas City Chiefs, San Diego has to figure out how to replace the talented defensive end.

The Chargers initially will rely on depth on the roster, including defensive linemen Darius Philon, Tenny Palepoi and Ryan Carrethers.

"We'll go with what we have," Telesco said. "There's not really much you can do about it."

Don't be surprised, however, if the Chargers add a couple bodies up front during final roster cuts in just over a week, if Telesco feels the talent on the waiver wire is better than what's on the roster.

San Diego is high on the league's claim list because of the team's high draft status this year.

The Chargers were compelled to create a deadline for Bosa to sign this week because the team is running out of practice time to get him ready for the regular season.

More than half of San Diego's padded practices are in August. The Chargers will have just one more padded practice before the season opener. After that, teams get 14 fully padded practices during for the regular season -- about one per week to get in work for game days.

There's little concern that Bosa will report to Chargers Park in good physical condition.

However, the team does have concerns about Bosa getting into football shape, including the physical pounding needed to prepare for game days, along with learning what defensive coordinator John Pagano has in store for his role on the field.

And the Chargers did not want to pay for a player who might not be available to play to his full potential for the first couple of weeks of the regular season.

So for now, the Chargers and Telesco will have to rely on players currently available on the roster.

If Bosa eventually joins the team, he likely will receive a restructured offer sheet that reduces the amount he could have signed for this week, the thought being he would not be available for a full, 16-game season because of his lateness in reporting to Chargers Park.

Bosa cannot be traded this season. According to NFL rules, he had until Aug. 9 to sign his contract in order for the Chargers to trade his rights to another team. If he were to remain unsigned this season, he is permitted only to sign with the Chargers until the first day of the 2017 draft.

So once again, this contract stalemate remains in a holding pattern until someone budges.
