GLENDALE, Ariz. — Rookie T.J. Logan, a speedster who had been expected to return kicks and punts for the Arizona Cardinals, fractured his wrist in Thursday night’s Hall of Fame Game against Dallas.

Coach Bruce Arians said Saturday that Logan will undergo surgery and is expected to be sidelined for 12 weeks.

It’s a blow to the Cardinals, who had been impressed with Logan’s electric returns in the game and in workouts.

He was a fifth-round draft pick out of North Carolina. If he can return in 12 weeks, that would be the team’s bye week following Arizona’s game against the Los Angeles Rams in London. So there’s a chance he could be back for the Nov. 5 game at San Francisco.

In the meantime, Arians said several players will audition for kick and punt return duties.

BRONCOS: A scrimmage on Saturday failed to clarity who Denver’s starter at quarterback will be when the season begins next month.

Trevor Siemian and Paxton Lynch have spent training camp trying to entrench themselves as the No. 1 quarterback.

But with a few days before the first preseason game, there is no clear winner. Siemian, who won the starting job last year over veteran Mark Sanchez and Lynch, began to separate himself this week. But he didn’t lay claim to the No. 1 spot in Saturday’s scrimmage.

EAGLES: Executive Jim Gallagher has died after spending almost a half-century with the team. He was 88.

The team said he died Friday but did not give other details.

Gallagher joined the Eagles in 1949 and retired in 1995.

He was named personnel director in 1957 and later was public relations director, sales and marketing director, alumni relations director and traveling secretary.

VIKINGS: Minnesota locked up another core piece of its defense, agreeing to a contract extension with nose tackle Linval Joseph.
