No teams attended Terrell Owens' workout in Calabasas, Calif., on Tuesday, but the 37-year-old receiver said he was confident that he showed enough that teams will be interested.

The free-agent receiver is unsigned after tearing his anterior cruciate ligament and having surgery in early April. He participated in some drills and caught passes Tuesday in the workout that was televised on ESPN and the NFL Network. He did not run the 40-yard dash.

"I definitely feel there are some teams out there that are interested," he told ESPN.

Agent Drew Rosenhaus said Wednesday in an interview with ESPN Radio's "Mike and Mike in the Morning" that no teams have called as of Wednesday morning, but he's sure NFL teams were watching Owens' workout on TV.

"Just because they weren't there doesn't mean they weren't interested," he said. "I can guarantee that all 32 teams were interested."

Rosenhaus said that from his conversations with teams before the workout that he wasn't surprised by their absence. He said the workout was organized to "create interest. We were trying to create a buzz."

And he believes that Owens opened some eyes Tuesday.

"I think that teams see that Terrell is healthy, that he is ready to play football," Rosenhaus said.
