He said he never got the ball so I'm assuming the other team won the toss, got the ball, kicked a FG and got the win right away.
The only question may be did time expire? It is easy in madden with 6 minute quarters to keep the ball the entire quarter. If he was playing someone online I could easily see them being smart enough to run the clock down and kick a last second FG to win. (Heck, I've come close to having a single drive last an entire half before online). If this was the case then the win was legit for the other guy.
I have yet to have an OT game online. ☹️
