LeSean McCoy -- Checks Out Hot News Reporter ... During Traffic Report

He can stop on a dime ... but LeSean McCoy also stops for a dime piece.

The Eagles superstar stopped by FOX 29 in Philly today to talk football, his upcoming charity event and all things Philly.

But the best part of the segment was when one of the newscasters walked Shady over to Kacie McDonnell -- the woman doing the traffic report ... and LeSean had to stop to take in the sights.

Can't really blame the guy ... Kacie's pretty smokin' hot ... and the proof is on her Instagram page.

Of course, Shady handled himself like a perfect gentleman ... which is good, 'cause Kacie's kinda taken -- she's dating NFL rookie Aaron Murray ... who just got drafted in the 5th round to the KC Chiefs.
