Livingston defender Cammy Kerr thinks Hearts' title challenge has "run out of steam", particularly with injuries to key players.
The Jambos are currently top of the Premiership table but could drop off top spot depending on results this weekend.
Derek McInnes' side are two points clear of Rangers in second and three ahead of Celtic in third, who have a game in hand.
If Hearts don't win on Sunday and Rangers do, they'll slip off the top of the table for the first time since August.
They're at home to John McGlynn's high-flying Falkirk on Saturday and Kerr believes, with the pressure off the Bairns they've got a solid chance of getting a result.
"I think honestly Falkirk will get a result," Kerr told the BBC's Scottish Football Podcast.
"I do believe that. They have been to Tynecastle in the cup already and gave them a shock and that could even play a part at the weekend.
"Falkirk are under no pressure. It's a great place to go and play at Tynecastle and all the pressure is on Hearts.
"Everyone has spoken about Hearts all season, how good they've been and rightly so.
"My opinion is that they've just run out of steam.
"I think at the time Lawrence Shankland and Cammy Devlin came out the squad, that's coincided with the results just dipping ever so slightly. I think next season will be where you really do see Hearts kind of push on.
"It'll be a really interesting game at the weekend and Falkirk might just pick up the points."
