29 MINS: Honduras goes short with its corner and Palma has a go at goal. The shot is well-hit and long but Ochoa drops to his knees and corrals it.
27 MINS: Honduras wins its first corner kick of the match but that will have to wait, as the referee signals for a hydration break. With the temperature currently 90 degrees in Guadalajara, don't be surprised if we see another hydration break later on.
25 MINS: A little flair from the USYNT, as Mihailovic nutmegs a Honduras defender but his ball from Jesus Ferreira is a tad too long. Better from the Stars and Stripes.
21 MINS: Another long-range effort for Honduras, Luis Palma testing Ochoa from distance. The Real Salt Lake keeper has been the busier of the goalkeepers so far, although his three saves have all been of the straightforward variety.
18 MINS: Honduras danger man Edwin Rodríguez has a shot from distance which is comfortably caught by Ochoa in the U.S. goal. As Jeff Carlisle pointed out pregame, controlling Rodriguez will be a big key for the United States defense.
16 MINS: Not to be outdone, Lewis tries to one-up Rosales but also blazes wide. Both teams not shy in the early stages.
14 MINS: A speculative effort from Honduras' Joseph Rosales soars over as Honduras registers its first shot attempt of the match.
12 MINS: CHANCE! The ball runs through for Jonathan Lewis but he can't get his boot across it and fires wide. U.S. starting to mount some pressure here.
10 MINS: The subsequent corner is dealt with easily by Honduras. Not the best delivery from Mihailovic.
8 MINS: The U.S. wins a free kick in the Honduras half and Djordje Mihailovic whips in a testing ball after an intricate training ground routine. Honduras keeper Alex Güity does well to punch clear but the U.S. will have the first corner of the match. Güity stays down initially after taking some contact but he will stay in.
5 MINS: The first chance of the game goes to Honduras with David Ochoa called upon to make a save. The flag did go up for offsides but an early scare for the United States.
1 MIN: AND WE ARE UNDERWAY FROM GUADALAJARA!
6:00 PM ET: It won't be long now as the teams have taken the pitch and are poised for the playing of the national anthems.
5:30 PM ET: With a half-hour until kickoff, let's check in with our U.S. soccer expert Jeff Carlisle to get his keys to the game:
1. U.S. attackers need to step up. The Americans have been relatively quiet offensively in this tournament and the fact that Jackson Yueill is playing in a more advanced role speaks to the fact that more is needed.
2. Keep Edwin Rodriguez in check. The U.S. defense has gotten better with each game. It'll need to continue that trend in order to contain Rodriguez, who tends to float around all over the field, though he'll be without sidekick Kervin Arriaga, who is suspended. Holding mid Andres Perea will need to be aware as well.
3. How effective will Hassani Dotson be? Dotson has been one of the better players for the U.S., but an ankle injury limited his training ahead of this match. Can he reprise his performances from earlier in the tournament? The level of Dotson's effectiveness could play a decisive role in what figures to be a closely-contested fixture.
5:00 PM ET: And the lineups are out ... with Jason Kreis making five changes from the side that lost 1-0 to Mexico on Wednesday night.
Justen Glad, Jesus Ferreira, Sam Vines, Jackson Yueill, and Jonathan Lewis are all drafted into the side, while midfielder Hassani Dotson starts despite initially being an injury question mark. For Honduras, key midfielder Kervin Arriaga misses out through yellow card accumulation.
4:50 PM ET: It's Matchday, as we are now just over an hour and a half away from kickoff between the U.S. and Honduras in the semifinals of CONCACAF Olympic qualifying! Remember to keep it locked here throughout the evening as we follow along with this pivotal match, with the winner clinching an all-important berth at this summer's Olympic Games in Tokyo.
