Watch: Houston guard Jamal Shead's incredible basket late caps off thrilling OT win over Texas A&M

Shead's basket turned the final seconds into a free-throw-off, which Houston won, taking the slugfest, 100-95. 

Down by as many as 13 points, Texas A&M looked dead in the water late in the second half, but a 13-3 run offered a chance at a shocking comeback. With Houston up 86-83 with 1.2 seconds remaining in the regulation, forward Andersson Garcia hit an incredible game-tying three-pointer at the buzzer, forcing the extra session. 

Houston ultimately prevailed as the Aggies ran out of steam in OT, outscored 14-9. 

Shead, who finished with 21 points and a team-high 10 assists, was one of four Cougars to post double figures. L.J. Cryer had 20 points and Emanuel Sharp led the team with 30 points, including seven three-pointers (7-of-14).

With the win, Houston advances to the Sweet 16 in Dallas, where No. 4 Duke will be waiting. The Blue Devils are coming off two impressive blowout wins, including a 93-55 victory over No. 12 James Madison on Sunday. 

The Cougars' victory helped mark only the fifth time since 1985 that each No. 1 and No. 2 seed in the NCAA Tournament advanced to the Sweet 16.
