Answer based on context:

For the fourth time in as many trips to the western United States, the Jets lost to the woeful Seahawks in Mike Holmgren's final home game as  the team's head coach. The loss dropped the Jets to 9-6 and out of first place in the AFC East. Jay Feely put the Jets on the board with a field goal eight minutes into the game and the lead held for most of the remainder of the first half. Seattle scored with thirty one seconds remaining in the half on a Seneca Wallace touchdown pass. Olindo Mare kicked two field goals in the second half, including one with 1:47 remaining to clinch victory for Seattle. Brett Favre was held without a touchdown pass for the Jets and threw two interceptions, and Thomas Jones was held to 67 yards. For the Seahawks Maurice Morris rushed for 116 yards on 29 carries and Wallace finished with 175 yards passing and his second-quarter touchdown.

Which plays were the only scores in the first half?
