Illinois' 21-17 win over South Carolina in the Citrus Bowl -- a historic marker for the Fighting Illini, who for the first time since 2001 eclipsed 10 wins in season -- was overshadowed by a bizarre feud between two of college football's most colorful head coaches.

Tempers flared at the Cheez-It Citrus Bowl on Tuesday between South Carolina and Illinois. After Illini defensive back Jaheim Clarke went down with an injury, his coach Bret Bielema walked over to check on him.

Shane Beamer erupted on Tuesday after Bret Bielema appeared to taunt South Carolina's coach during the Citrus Bowl:

Here is the everything South Carolina coach Shane Beamer said about the heated interaction between him and Bret Bielema during Citrus Bowl.

"Beamer could hardly believe it at first. He taunted Shane Beamer, and Beamer had enough and snapped," ESPN sideline reporter Quint Kessenich said.

The Cheez-It Citrus Bowl was one to savor as it featured all sorts of mind-blowing action, including a coaches' confrontation.

Beamer saw Bielema’s taunt and started charging forward screaming and pointing at the Illinois head coach. A number of staffers held him back and escorted him back to the sideline. “Shane just turned to me and said, ‘You saw what he did,’ ” said ABC sideline reporter Quint Kessenich.

Shane Beamer and Bret Bielema are no longer friends. After the head coaches for South Carolina and Illinois spoke glowingly of each other throughout the week leading up to Tuesday’s Citrus Bowl, all hell broke loose late in the third quarter when Bielema chose to taunt Beamer while tending to an injured player.

Shane Beamer's South Carolina squad lined up against Bret Bielema's Illinois squad in this year's Cheez-It Citrus Bowl after being two of the better squads in the sport throughout the regular season. However, in the third quarter of the New Year's Eve matchup, Beamer and Bielema were visually upset with one another on the field.
