That was some (cheapshot) hit - welcome to the NFL, Sav!
Anyway, at least he got up fairly quickly - considering.
Pinched the folllowing info from Bigfooty -
Both Dirk Johnson and Sav Rocca punted the ball like their jobs were on the line. Johnson averaged 43.7 yards on three punts, two of which landed inside the 20, and Rocca averaged 48.3 yards on four punts. But Johnson averaged 41 net yards compared to Rocca’s 39.5, a stat that has a lot to do with Rocca’s strong foot. Since Rocca can crush the ball, he sometimes has a tendency to outkick his coverage, which usually leads to a big return. Rocca said there was only [one] difference between kicking in the NFL and Australian Football League. “Just the balls,” Rocca said. “These balls are straight out of the packet and very, very slippery in your fingers. You just have to make sure you catch it and get it off right.”
And here's a detailed training camp report (its amazing the amount of even minor detail in NFL that gets reported by someone or other) -
2:17 PM: Now the focus shifts from kickoff returns to the punting contest. Dirk Johnson is up first, and boots three consecutive good kicks. Even more important that their distance (and they're between 45 and 50 yards), is they are well directed to the left side.
2:19 PM:
Sav Rocca takes his turn, and he is even more impressive today. His kicks are well directed to the left side too, and one of them goes about 65 or 70 yards. The smaller crowd that has come out for the special teams portion of practice voices its approval with a vigorous round of applause.
2:25 PM: The punters are switching off now in a back and forth battle. Johnson is pretty good today but so his Rocca. The big Australian native is more consistent today, and his lack of consistency has been the biggest criticism of him. Rocca has had only two sub-par punts so far, and neither was a particularly disastrous shank. This is out of about 10 to 12 kicks. Almost sensing what I'm writing, Johnson responds with three very good kicks - high, tight spirals that go about 45 to 50 yards. On the third the crowd takes a turn to applaud Johnson.
2:40 PM: The punters now move-up, with the line of scrimmage 45 yards from the end zone, and take turns working on trying to pin the team inside the ten-yard line. Dirk Johnson, who normally excels at this drill, boots a few into the endzone.
2:43 PM:
It's Sav Rocca's turn up, and he employs an interesting style when trying to pin teams deep. Normally Rocca punts a spiraling ball, like any other punter. Here, however, he kicks the ball end over end, and with great results. (Rocca here employs an Aussie invention - the good old drop-punt) The first punt hits at the five yard line and checks up like a pitching wedge. Of Rocca's six kicks, not one goes into the endzone, and all of them end up somewhere between the 10 and the 20.
2:49 PM: Also fielding punts right now with Bloom are J.J Outlaw and Greg Lewis. Sav Rocca finally boots a ball that rolls into the endzone, ending a very good streak for Rocca.
Consistency is supposed to be what Rocca lacks, but he has been more consistent than Johnson today.

Considering Johnson is a seasoned pro and was brought up with the game, compared to Sav with no previous experience, Sav has shown enourmous ability, so even if Philly play safe and stick with Johnson, Sav must be a good chance of then being picked up by another team at some stage in the up-coming season.
