After signing restricted free agent wide receiver Miles Austin to a six-year contract extension worth over $50 million, Dallas Cowboys COO and Director of Player Personel Stephen Jones says the team will not extend any more contracts.

"We can't extend ourselves out there any more," Jones said, according to Gerry Fraley of the Dallas Morning News.

Austin was the only one of the Cowboys' ten restricted free agents to receive a contract extension this year. The Cowboys are on target to spend in excess of $100 million in base salary and roster/signing bonuses in 2010, but may still be feeling the effects of spending nearly $40 million in signing bonuses for DeMarcus Ware, Roy Williams, and Igor Olshansky in 2009.

The Cowboys will also need to address new starting left tackle Doug Free, whose contract expires after this season.

"We have a lot of guys that we're going to have to deal with whenever things get ironed out," Jones added. "That's unfortunately what we're dealing with."
