can you knee a ball back to the goalkeeper
Back-pass rule While not an infringement of the back-pass rule, players are also prohibited from using a deliberate trick to pass the ball to the goalkeeper with a part of the body other than the foot to circumvent the rule. This would include, but not be limited to:
Lateral pass While a forward pass may only be thrown once per down by the team on offense from within or behind the neutral zone, there are no restrictions on the use of lateral passes; any player legally carrying the ball may throw a lateral pass from any position on the field at any time, any player may receive such a pass, and any number of lateral passes may be thrown on a single play.[1] Additionally, a player receiving a lateral pass may throw a forward pass if he is still behind the neutral zone, subject to the forward pass rules.[2]
