Task: Question Answering
Input (English): Passage: Hoping to rebound from their tough road loss to the Patriots, the Chiefs hosted their AFC West rival, the Oakland Raiders.  In the first quarter, Kansas City trailed early as Raiders kicker Sebastian Janikowski got a 56-yard and a 25-yard field goal. Chiefs quarterback Damon Huard suffered a neck injury in the first quarter and Tyler Thigpen substituted as quarterback for the remainder of the game. Huard was in for Kansas City's first two series, but didn't return after throwing an interception late in the second quarter. Marques Hagans, who was listed on the Chiefs' roster as a wide receiver, checked in as quarterback for several draw plays. The Chiefs announced at the end of the third quarter that Huard sustained "mild head trauma," a move deemed controversial as Huard never sought medical attention in the following days. Under Thigpen, the Chiefs' offense struggled to move the ball down the field. In using three quarterbacks, the Chiefs had only 65 net yards at halftime. Raiders RB Darren McFadden got a 19-yard TD run in the third quarter. Oakland increased its lead with Janikowski nailing a 40-yard field goal in the fourth quarter. The Chiefs would respond with rookie QB Tyler Thigpen completing a 2-yard TD pass to TE Tony Gonzalez, Kansas City executed a two-point conversion pass to rookie FB Mike Cox to make them within 8 points with just over five minutes remaining. The Chiefs' two-point conversion was the team's first in two years. Kansas City lost its opportunity to tie the game as the Raiders pulled away with RB Michael Bush getting a 32-yard TD run. The Chiefs' defense allowed the third-highest total yards on offense in franchise history. JaMarcus Russell completed only 6 of 17 passes for 55&#160;yards and led the Raiders to a 15-point victory. Following the game, Chiefs RB Larry Johnson voiced his displeasure with the Chiefs' offense and his role with the team. With the loss, the Chiefs fell to an 0-2 record for the third consecutive year. Kansas City's 11-game losing streak (2007-2008) is the longest in franchise history. The Chiefs also lost their second consecutive game to the Raiders for the first time since 2001. 
Question: How many total yards did JaMarcus Russell's completed passes add up to? 
Answer type: Number 
Output (English): 55.
