Read this article and answer this question Staying at home, the Panthers played a Week 5 match-up against the visiting Cleveland Browns.  Even though the Browns would score first on a 41-yard field goal by Phil Dawson, the Panthers struck big as rookie CB Richard Marshall took an interception 30 yards for a touchdown.  In the second quarter, Carolina increased its lead, as QB Jake Delhomme threw a 17-yard TD pass to WR Keyshawn Johnson for the only score of the period (and in fact the only offensive touchdown of the game for either team).  In the third quarter, both teams managed to get a field goal, as kicker John Kasay got on from 24 yards out, while Dawson nailed a 47-yarder.  In the fourth quarter, the Browns drew closer, as Dawson kicked a 22-yard field goal, but Kasay helped Carolina get a 19-yard field goal.  The Panthers would allow one more Dawson field goal (a 32-yarder), but in the end, Carolina would walk away with their third-straight win while improving to 3-2.
