Terrell Owens' attempt to make an NFL comeback may have a chance.

The 44-year-old posted a video to Instagram on Monday in which he appeared to run a 40-yard dash. Atlanta Falcons wide receiver Julio Jones, who's been working out with Owens this offseason - reportedly drawing the ire of his own team - said he clocked him at 4.43 seconds. A third individual at the workout displayed a time of 4.44 seconds on his stopwatch.

Owens last played for the Cincinnati Bengals in 2010 at age 37.
