Terrell Owens is a freak of nature.

After catching 1,078 passes for nearly 16,000 yards and 153 touchdowns, earning election into the Pro Football Hall of Fame in February, Owens wants to prove he can still play in the league, even at the age of 44.

Owens showed off his speed on Monday, with two different stopwatch operators clocking him covering 40 yards in 4.43 and 4.44 seconds.

It remains to be seen whether or not some NFL team will actually give Owens a shot at making a comeback, but his 40-yard sprint is very impressive, to say the least.
