That is good news for a defense that can't afford to be without him very long.
Weatherspoon, the No. 19 pick in the 2010 draft, is Atlanta's lone elite linebacker. He plays every snap unless he is injured.
Falcons coach Mike Smith said Weatherspoon likely won't make his preseason debut until next week at Tennessee.
Weatherspoon left practice on Aug. 5 with a dislocated left finger that had an open wound. He was limited in participation on Monday with two fingers taped heavily together under a protective glove.
The team didn't make Weatherspoon available to speak with reporters.
"We didn't want him to have any contact quite yet, but we wanted to get him back out and let him work through drills," Smith said Monday night. "He will progress each day a little bit more."
Robert James has been almost exclusively a special teams player, but the rest of the depth chart consists of Pat Schiller, Nick Clancy, Joplo Bartu, Brian Banks and Paul Worrilow -- none of whom has played in an NFL game.
Competition is wide open, and Smith indicated that reserves who didn't get first- and second-quarter snaps last week could have some chances when Atlanta (0-1 preseason) visits Baltimore (1-0) on Thursday.
"Often times, the first time out, they're playing in the third and fourth quarter," Smith said. "We'd surely like to see some of these guys compete against some of the front-line players that will be in playing in (the regular season)."
TE Tony Gonzalez, on leave from the team since the second day of camp to spend time with his family, is likely to return to practice early next week and be in uniform when the Falcons visit Tennessee. Gonzalez, the NFL's No. 2 career leading receiver, was given permission to miss time this month after signing a one-year contract in March. The 37-year-old Gonzalez will retire after the season. ... Smith indicated that WR Julio Jones, who missed last week's game because of sore hamstrings, likely will play at Baltimore. Jones has practiced the last three days.Information from The Associated Press was used in this report.
