The Denver Broncos have made contract offers to star wide receiver Demaryius Thomas and tight end Julius Thomas and will continue negotiating with both players after training camp opens July 24, Broncos general manager John Elway said Wednesday.

"Nothing is going to get done before camp, but we'll keep talking to them in camp," Elway told USA TODAY Sports after playing a practice round of golf at the American Century Championship near Lake Tahoe.

Both Thomases are entering the final years of their rookie contracts, Demaryius as a first-round pick from 2010, and Julius as a fourth-rounder in 2011. They combined for 157 catches, 2,218 receiving yards and 26 touchdowns in Denver's record-setting offense last year.

The Broncos declined to continue contract talks into training camp two years ago with left tackle Ryan Clady (he reached a long-term deal with the team last July after receiving the franchise tag), but Elway said he won't break off talks with either Thomas until early August.

"I'm never going to go into the season, but the first couple of weeks, we can continue to talk about it. After the second week of the preseason, we'll want to have had something done, one way or another."

Demaryius Thomas, coming off back-to-back 1,400-yard seasons, is on the verge of superstardom and fast becoming one of the league's elite receivers. He caught 14 touchdowns last year, plus three more in the postseason.
