ENGLEWOOD, Colo. -- Denver Broncos defensive tackle Ty Warren will undergo surgery Tuesday to repair his partially torn right triceps.
They should have a better idea if that's possible after the operation.
"He's not going to be on IR at this point, so nothing's ruled out," Fox said.
Warren was the Broncos' top free-agent acquisition, two weeks ago signing a two-year, $8 million deal that included a $2.5 million signing bonus and $1.5 million in salary this season.
Warren, who was cut by the New England Patriots last month, spent last season on IR with a hip injury.
Warren was hurt during practice Monday after lining up alongside Marcus Thomas, who strained his right pectoral muscle during a 1-on-1 drill. Minutes later, Warren was hurt during a 9-on-7 team drill.
Thomas is expected back by mid- to late September. For the first time since being hurt, Thomas didn't have his right arm in a sling while on the sideline Thursday morning.
The Broncos claimed defensive tackle DeMario Pressley off waivers from the Cincinnati Bengals. With the No. 2 waiver claim until the third week of the regular season, the Broncos are expected to add some more beefy bodies in the coming weeks.
In addition to defensive tackle, they're not very deep along the offensive line, and a play Wednesday night threw a scare into the Broncos' front office when pass-rusher Elvis Dumervil and starting offensive tackles Ryan Clady and Orlando Franklin got tangled up during an 11-on-11 play and all three ended up on their backs.
Dumervil and Franklin shook it off, but Clady had his left knee checked out by the training staff and sat out the rest of practice. He returned Thursday.
If the NFL decides to let teams keep their 90-man rosters until after the final preseason weekend, nearly 1,200 players will flood the market on Sept. 3 when final cuts are made. Those with less than four years of experience will be subject to the waiver-wire process. Others will be free to sign anywhere.
