Rafael Nadal Vs. Dusan Lajovic Live Stream & Radio: French Open 2014, Round 4 (WATCH/LISTEN)

Rafael Nadal plays Dusan Lajovic on Monday in the fourth round of the 2014 French Open. The match is slated for 7:00 a.m. ET. Watch the live stream or listen to the radio broadcast via the links provided below.

Nadal, ranked No. 1 in the World, defeated Leonardo Mayer on Saturday in straight sets. The Spaniard hasn't dropped a set yet in this year's Roland Garros, but that could change as he struggles with a back injury.

Nadal told reporters after the match his back is bothering him and causing him to hit slower serves.

"During my career, I had (a) few problems," Nadal said, via the Associated Press. "... Hopefully will not be (the case the rest of the way in the tournament). I served more slowly since I started feeling the pain."

He noted he has been wearing tape on his back for additional support, according to the Associated Press.

Lajovic, ranked No. 83 in the World, also hasn't dropped a set en route to the fourth round. He defeated Federico Delbonis, Jurgen Zopp and, most recently, Jack Sock.

The 24-year-old Serb doesn't have much experience in Grand Slams, and he's never faced Nadal.

"Well, it's my first Roland Garros main draw appearance and first time in the fourth round, so I can't be more happy than this," Lajovic told the tournament's official website on Saturday. "Maybe to play Rafa on Chatrier is one of the biggest dreams and biggest challenges. So for sure it's not going to be easy."

Lajovic also isn't shy about asking for tips on how to play Nadal.

"Yeah, I will try to ask everybody some tips against Rafa, yeah," Lajovic said with a smile. "You need to have a lot of tips and confidence to beat him, but I hope to enjoy the match if he wins and to give my best."
