Horton recorded three receptions for 26 yards on six targets in Monday's 34-17 loss to the Bears.
Horton was on the field for 43 of the Seahawks' 63 offensive snaps, with his 68 percent share representing a season high. The six targets were also a season-best total for Horton, who was the main beneficiary of extra playing time due to the absence of Rashid Shaheed (knee). If Shaheed is cleared to play in the Seahawks' Week 9 game against the Cardinals, Horton will likely see his role get reduced.
