Pulled foot ?

[TERRY1]

R1 on 3 R2 on 2 B1 BU in C 2 outs. Batter hits to F6 deep in hole F6 fire it to F3 BU calls the out. R1 crosses hp R2 has rounded 3b still heading home. Definse heres the out call and is leaving the field and R2 contiues and cross hp. Definsive Coach ask PU for an appeal of F3 pulling foot. PU refers coach to BU for appeal. BU goes to PU for help on pulled foot of F3. PU says foot was pulled. BU awards 1ST base to batter runner. Score both runs or put R2 back on 3? R2 probaly would not have scored if there would have been a safe call originally. FED rules. By the way I was the lucky BU.

Thanks
