The NFL's recent rate of non-contact injuries to the knee, ankle and foot is roughly the same on natural grass and artificial playing surfaces, according to internal league data.

The numbers contradict anecdotal observations this season from players, agents and coaches. Many have called for the league to convert all surfaces to grass in response to a series of high-profile injuries on artificial turf. 

The NFL has no plans to do so, Jerry Jones said Tuesday morning on 105.3 The Fan, citing the current data.

"Not at all," said Jones, whose team plays in one of 16 NFL stadiums with an artificial surface. "And it's not because we have the surface that we have. Our league stats don't see issues with the type surface that we have as opposed to natural grass. We don't see issues. No facts bear that out."
