Vernon Davis has said that he needs to work on his chemistry with Colin Kaepernick.
The tight end has yet to connect with the San Francisco 49ers starting quarterback for a touchdown since he replaced Alex Smith last month.
The 28-year-old told the Sacramento Bee: "We don't have it. You have to expect [that because] he just stepped in.
"Me and Alex, we've been there. It takes time. It took time for me and Alex to get like that. It's like it's starting all over again, especially for me."
Davis has just four catches in his last four games for a total of 29 yards.
The 49ers face the Seattle Seahawks on Monday.
