Davis, at 6-foot-1, 308 pounds, ran an official clocking of 4.75 seconds in the 40-yard dash Saturday night and Gallimore, at 6-2, 304 pounds, clocked an official time of 4.79 seconds.

According to ESPN’s Stats and Information, those times made the pair the only defensive linemen who weighed more than 300 pounds to clock sub-4.8 40s since 2006. Davis’ twin brother Carlos (6-2, 313 pounds) had an official 40 time of 4.82.
