49ers star Dre Greenlaw is EJECTED for scrap with Eagles' head of security as tempers boil over in NFC title game rematch

San Francisco 49ers linebacker Dre Greenlaw has been ejected for a scrap with the Philadelphia Eagles' head of security, as tempers boiled over in the rematch of the NFC Championship game from last season. 

The incident took place midway through the third quarter of Sunday's game, with the 49ers up, 21-6. 

Eagles quarterback Jalen Hurts had completed a pass to DeVonta Smith for a first down. Smith was then tackled by Greenlaw. 

Dom DiSandro, a constant presence on the Eagles' sideline and whenever players are out in public, pulled Greenlaw off Smith after the reception. He's also known as 'Big Dom' to Eagles fans.

Greenlaw popped up and reached over two officials to touch DiSandro's face with a closed fist.

Greenlaw was ejected. 

DiSandro also was later told to leave and walked to the locker room to a roaring ovation from Eagles fans. 

The game was a rematch of last season's NFC championship game, won by the Eagles. 

Before Greenlaw was ejected, the officials had a lengthy discussion with Eagles head coach Nick Sirianni, who was pleading for the defensive player to leave the field.

Once the call had been made, Niners coach Kyle Shanahan was visibly angry with the officials, storming onto the field and yelling at the referees. 

Before his ejection at Lincoln Financial Field - home of the Eagles- Greenlaw led the Niners in tackles (seven). 

He has a history of drawing unnecessary roughness penalties, as he's had two others this season and five in his career. 

The Niners ended up defeating their rivals, 42-19, as they go 9-3 - a game behind the 10-2 Eagles. Ahead of Sunday's game, Philly had a two-game advantage of San Fran'.
