Birmingham City manager Lee Clark lost 19-year-old Will Packwood with a broken fibula and tibia, which will rule him out for the rest of the season.
Packwood and Becchio collided innocently soon after the equaliser (see video above).
"It took the gloss off a fantastic performance," said Clark. "Will's young team-mates and friends are distraught, they were in tears out there.
"I said, 'Let's try and win the game for Will'. We couldn't quite do it but I thought we deserved to do so.
"We will give him as much care and support as possible and have him back fit and strong for next season.
"We should be celebrating a fantastic performance by my young players, but this is a real downer. I heard the snap and was hoping it was a shin pad. It was an innocuous one with two players going for the ball."
